Search warrant documents obtained Thursday by NBC 7 San Diego reveal that explosive devices, a map of Yosemite and assault weapon-style ammunition were among the items investigators found at the burned-out property of kidnap and murder suspect James Lee DiMaggio, 40.

According to the court documents, investigators searching DiMaggio’s property in the community of Boulevard near San Diego also discovered camping equipment, a gas can and a handwritten note.

Newly-unsealed search warrants reveal details of the events leading up to the kidnapping of San Diego teen Hannah Anderson.

Arson wire, two boxes with red stains on them, a tarp and a map of Yosemite were also seized during the search – the latter being a possible clue as to where DiMaggio intended to take 16-year-old Hannah Anderson.

The searches also turned up a handcuff box, a red dog leash and a swatch of hair among the remaining rubble of DiMaggio's property. Also, military assault weapon-style ammunition was recovered.

There could, of course, be an innocent explanation for all those items, and the court documents do not specifically connect any of those objects to Dimaggio's crimes.

In the application for the search warrant, the law enforcement officer told the judge he was specifically looking for objects and weapons that can inflict blunt force trauma.

Other search warrants unsealed on Wednesday revealed that a crowbar was found near Christina Anderson's head. Investigators were likely searching for more evidence of this kind in the rubble of DiMaggio's home and garage.

Officials say DiMaggio fired at least one shot himself from his own weapon during the confrontation in the wilderness, though further details have not yet been released pending the ongoing investigation.

Hannah has since reunited with her family and returned home to San Diego.

Ed. note: NBC 7 News initially reported on a DNA test kit listed among the evidence removed from Christina Anderson's vehicle on the search warrant documents. A sheriff's department spokesperson clarified the contents of the list explaining the DNA test kit was used by investigators and not found in the vehicle.
